I have it installed on my Vista machine with Office 2007. I’m at work right now and don’t have the Vista machine handy, but if I remember correctly, it is tools/options. It comes up as one of the tabs inside there.

In normal circumstances, if you shared computer with other people, would you want them to install things to your account as well?

In normal circumstances, they don’t have admin rights, also no installation. It’s a bad habit to work as admin.

And because you don’t have a ‘personal’ program files folder, it’s a question of setting the security on folders or install the shortcut in ‘all users’ or not.
Normally this is an option: Install “only for me” or “all users”.

Also PA installs the shortcut to ‘All users’ and it’s accessible to all users.
Why not also the add-in?

To choose option 2 the user that’s installing it should have admin rights. This should satisfy safe computing practices as well as satisfy users by giving them the option to choose depending on their scenario of multi-user or single-user pc.

It would appear you’ve got a multi-user setup and would like to not need to give the other user admin privileges or else you would like to use your pc under a non-admin account for security purposes. It sounds like the devs will work towards making the install choices - regarding which users to install the plugin for -optional, so that should fix this issue.

In the meantime, what about making your non-admin account an admin temporarily, installing PAOP, then change the account back to a non-admin and see if you can then run the plugin succesfully as the non-admin user? I know it’s not the ideal method but maybe you can get this to work while a better solution is cooked up.
